CCTV News: Shenzhou 20 astronaut crew has been working and living in China's space station for more than 20 days. Last week, the crew carried out practical space science experiments, pressure emergency drills throughout the system, and inspection and maintenance of the station equipment. The three astronauts were full of motivation and energy.

"Experiment" and "draft" are online at the same time

Various studies in the National Space Laboratory continue to be carried out. Last week, the Shen Twenty-Cross Group observed the microbial effect mechanism research sample in the cell tissue culture module in the biotechnology experimental cabinet. Compared with the video picture of the previous issue, the appearance of the sample has changed significantly. Recently, with the close cooperation of ground scientific researchers, the Shen Twenty Crew completed the first full-system pressure emergency drill since its entry, simulating the entire process of emergency response between astronauts and ground personnel "coordination of heaven and earth" when the space station faces internal pressure loss.

In-site equipment inspection and maintenance continues

The low-temperature storage environment is a necessary condition for conducting space biological science experiments. The low-temperature storage device in the Wentian Experimental Cabin can provide my country's space station with a long-term and long-lasting low-temperature biological sample storage function. Last week, the crew inspected it and completed a status check. In addition, the crew conducted regular inspections and maintenance of the three sets of out-of-cabin space suits in the station, and completed relevant equipment status inspections and settings.

The Shenzhou 20th Crew conducts station management to create a comfortable environment

While completing space science experiments and experiments, the Shenzhou 20th astronaut crew also regularly completes material sorting and transfer, environmental cleaning and maintenance, etc., to maintain the "Space Home" clean and orderly.

Carry out station management to create a comfortable environment

Last week, the crew cleaned the environment in Tianhe core compartment, node compartment, Wentian experimental compartment, and airlock compartment as planned, and sorted out and transferred relevant materials. In addition, garbage transfer and storage work has been completed.

Health maintenance and guarantee are carried out at all times

In terms of health maintenance and guarantee, in addition to daily physical exercises, the crew also completed a number of medical examinations such as electrocardiogram examination, dynamic electrocardiogram measurement, and exercise lung function examination to obtain relevant data to help ground scientific researchers closely grasp the health status of the three astronauts.
